Objective To find out about the current health situation of the elderly in the Beijing area and their health care needs so as to provide basis for the formulation of health care policies for the elderly by the government and relevant departments and for the development of health care programs for the elderly in accordance with their needs. Methods A sample survey, covering such topics as the health situation, medical treatment, nursing, rehabilitation and health care needs of the elderly and community health service, was made of 2 487 elderly people aged 60 and above in different parts of Beijing, including the city proper, the part linking city and country, and the suburbs. An analysis was then made of the difference in the health situation and health care needs of the elderly between various parts and populations. Results Chronic diseases constituted the major health problem for the elderly, with hypertension, coronary heart disease, osteoarthrosis, and cerebrovascular disease ranking in the first four places and the incidence of diabetes increasing rapidly. About 10 percent of the elderly, who suffered from somatic dysfunction, had reduced daily life skills and needed assistance from others. An increased number of elderly people also meant a greater demand for medical and nursing services. Community health service, the advantages of which bacame increasingly manifest, was thus popular with the elderly. Financial difficulty was the chief factor affecting the elderly in their seeking medical service. Conclusion The elderly is a weak population in health. With the aging of the general population, the health care needs of the elderly are on the rise. As health is the major factor affecting the life quality of the elderly, enhanced efforts in the prevention and treatment of chronic diseases ought to be taken as the central task in the health care of the elderly. They are also the key to improving the life quality of the elderly.

Objective:To explore the diagnostic value of the serial position effect combined with delayed recall of auditory verbal learning test in diagnosing the elderly patients with different levels of cognitive impairment.Methods:A total of 310 subjects were enrolled and divided into three groups: the normal control group(NC group, n=128), the mild cognitive impairment group(MCI group, n=133)and the mild Alzheimer's disease group(mild AD group, n=149)matched for gender, age and education level.Comprehensive neuro-psychological tests were performed on all subjects, and the Auditory Verbal Learning Test-Huashan version(AVLT-H)was used to analyze the serial position effect.Results:There were significant differences in the primacy effect of the second and third time of immediate recall, short-term and long-term delayed recall among the three groups( P<0.05), but no difference was found in the recency effect between the MCI and mild AD groups( P>0.05). The long-term delayed primacy effect combined with the short-term delayed recall showed a better validity to distinguish those elderly subjects with different levels of cognitive impairment than other memorial indexes, and the correlative sensitivity and specificity were 83.21% and 71.43%(NC group vs.MCI group), 85.71% and 92.86%(NC group vs.mild AD group), 66.67% and 75.57%(MCI group vs.mild AD group), respectively. Conclusions:The long-term delayed primacy effect combined with the short-term delayed recall can assist in distinguishing elderly patients with different levels of cognitive impairment.

Objective Abnormal activation of mitogen-and stress-activated kinase (MSK1) plays an important role in the development of various cancers.This study was to explore the effect of small interfering RNA (siRNA)-mediated MSK1-silencing on the proliferation of human nasopharyngeal carcinoma (NPC) cells and its underlying mechanism.Methods The siRNA vector targeting MSK1 was constructed and transfected into CNE2 cells, and the NPC cell line stably expressing MSK1 was established.Then the cells were divided into a blank control (without transfection of the plasmid), a negative control (with stable transfection of the negative control plasmid), and an experimental group (with stable transfection of the positive recombinant plasmid).The expressions of MSK1 mRNA and protein were detected by real-time quantitative PCR and Western blot, respectively, the proliferation of the cells determined by CCK-8 and colony formation assays, the cell cycles analyzed by flow cytometry, the level of histone H3 phosphorylation at Ser10 examined by Western blot, and The transcriptional activity and expression of the c-jun protein measured by dual-luciferase reporter gene assay and Western blot.Results Compared with the blank control, the inhibition rates of cell proliferation at 48, 72 and 96 hours were significantly reduced in the experimental group (P<0.05), and so were the colony formation ability of the cells (P<0.01) and the expression and transcriptional activity of the c-jun protein (P<0.05).In comparison with the negative control, the experimental group showed significant decreases in the rate of cell growth after 24 hours, the inhibition rates of cell proliferation at 48, 72 and 96 hours (P<0.05), the number of formed colonies ([221.00±20.08] vs [99.67±15.57] / 300 cells, P<0.01), the proportion of S-phase cells (P<0.01), and the expression of the c-jun protein in the CNE2 cells ([100.00±0.00] vs [48.77±10.71] %, P<0.05), but a remarkable increase in the percentage of G0/G1-phase cells (P<0.01).Furthermore, histone H3 phosphorylation at Ser10 was markedly reduced (P<0.01) but no significant change was observed in the expression of the total c-jun protein in the experimental group.Conclusion Knockdown of MSK1 using siRNA can significantly inhibit the growth and proliferation of CNE2 cells, which may be closely related to the decreased phosphorylation of histone H3 and subsequently down-regulated transcriptional activity of c-jun.

Objective To study the effect of intervention on blood pressure and incidence of cerebrovascular diseases. Methods In 1987, two cohorts population were selected in urban areas of Changsha . One was intervention group , another was control group. Baseline blood pressure levels were investigated and the events of stroke were collected. Results After 14 years, the cumulative stroke events were 89 in the intervention group and 128 in the control group; the mean blood pressure increased with statistical significance in each group except diastolic pressure in intervention group, but the control group increased more significantly; the analysis of Kaplan-Meier displayed that the rate of non-stroke events were higher in intervention group than that in control group and the analysis of COX regression indicated that the risk for stroke-events were 1.4 times higher in control group. Conclusions The intervention of risk factors can delay the increase of blood pressure by aging and reduce the risk of stroke-events.
